Hello guys i want to show the date picker(end date) after the date select from the start date.The end date picker will display date after the from date.End date will display date

Solution 1:

     fromdate = (EditText) findViewById(fromDate);
    todate = (EditText) findViewById(R.id.todate);
    fromdate.setOnClickListener(newView.OnClickListener() {
        @OverridepublicvoidonClick(View view) {
            showTruitonDatePickerDialog(view);
        }
    });
    todate.setOnClickListener(newView.OnClickListener() {
        @OverridepublicvoidonClick(View view) {
            showToDatePickerDialog(view);
        }
    });
}
publicvoidshowTruitonDatePickerDialog(View v) {
    DialogFragmentnewFragment=newDatePickerFragment();
    newFragment.show(getSupportFragmentManager(), "datePicker");
}

publicvoidshowToDatePickerDialog(View v) {
    DialogFragmentnewFragment=newToDatePickerFragment();
    newFragment.show(getSupportFragmentManager(), "datePicker");
}

publicstaticclassDatePickerFragmentextendsDialogFragmentimplementsDatePickerDialog.OnDateSetListener {
    @Overridepublic Dialog onCreateDialog(Bundle savedInstanceState) {
        // Use the current date as the default date in the pickerfinalCalendarc= Calendar.getInstance();
        intyear= c.get(Calendar.YEAR);
        intmonth= c.get(Calendar.MONTH);
        intday= c.get(Calendar.DAY_OF_MONTH);
        DatePickerDialog datePickerDialog;
        datePickerDialog = newDatePickerDialog(getActivity(),this, year, 
        month,day);
        return datePickerDialog;
    }

    publicvoidonDateSet(DatePicker view, int year, int month, int day) {
        // Do something with the date chosen by the user
        fromdate.setText(day + "/" + month  + "/" + year);
    }

}

publicstaticclassToDatePickerFragmentextendsDialogFragmentimplementsDatePickerDialog.OnDateSetListener {
   // Calendar startDateCalendar=Calendar.getInstance();@Overridepublic Dialog onCreateDialog(Bundle savedInstanceState) {
        // Use the current date as the default date in the pickerStringgetfromdate= fromdate.getText().toString().trim();
          String getfrom[] = getfromdate.split("/");
        int year,month,day;
             year= Integer.parseInt(getfrom[2]);
             month = Integer.parseInt(getfrom[1]);
            day = Integer.parseInt(getfrom[0]);
        finalCalendarc= Calendar.getInstance();
        c.set(year,month,day+1);
        DatePickerDialogdatePickerDialog=newDatePickerDialog(getActivity(),this, year,month,day);
       datePickerDialog.getDatePicker().setMinDate(c.getTimeInMillis());
        return datePickerDialog;
    }
    publicvoidonDateSet(DatePicker view, int year, int month, int day) {

        todate.setText(day + "/" + month  + "/" + year);
    }
}

I choose a start date as....1/09/2017 Then i open a end date it displays from....2/09/2017

Solution 2:

try to use this code

publicstaticbooleanisDateAfter(String startDate,String endDate)
    {
    try
    {
        String myFormatString = "yyyy-M-dd"; // for exampleSimpleDateFormat df = newSimpleDateFormat(myFormatString);
        Date date1 = df.parse(endDate));
        Date startingDate = df.parse(startDate);

        if (date1.after(startingDate))
            returntrue;
        elsereturnfalse;
    }
    catch (Exception e) 
    {

        returnfalse;
    }
}

It return true if enddate is after start date.

Solution 3:

Define startDateCalendar like

Calendar startDateCalendar=Callendar.getInstance();

And update fragments code

publicstaticclassDatePickerFragmentextendsDialogFragmentimplementsDatePickerDialog.OnDateSetListener {

        @Overridepublic Dialog onCreateDialog(Bundle savedInstanceState) {
            // Use the current date as the default date in the pickerfinalCalendarc= Calendar.getInstance();
            intyear= c.get(Calendar.YEAR);
            intmonth= c.get(Calendar.MONTH);
            intday= c.get(Calendar.DAY_OF_MONTH);
            DatePickerDialogdatePickerDialog=newDatePickerDialog(mActivity,this, year, month,day);
            datePickerDialog.getDatePicker().setMinDate(System.currentTimeMillis());
            // Create a new instance of DatePickerDialog and return itreturn datePickerDialog;
        }

        publicvoidonDateSet(DatePicker view, int year, int month, int day) {
            // Do something with the date chosen by the user

            fromdate.setText(day + "/" + (month + 1) + "/" + year);
            startDateCalendar.set(Calendar.YEAR, year);
            startDateCalendar.set(Calendar.MONTH, month);
            startDateCalendar.set(Calendar.DAY_OF_MONTH, day);
        }   }

    publicstaticclassToDatePickerFragmentextendsDialogFragmentimplementsDatePickerDialog.OnDateSetListener {

        @Overridepublic Dialog onCreateDialog(Bundle savedInstanceState) {
            // Use the current date as the default date in the pickerfinalCalendarc= Calendar.getInstance();
            intyear= c.get(Calendar.YEAR);
            intmonth= c.get(Calendar.MONTH);
            intday= c.get(Calendar.DAY_OF_MONTH);

            DatePickerDialogdatePickerDialog=newDatePickerDialog(getActivity(),this, startDateCalendar.get(Calendar.YEAR), startDateCalendar.get(Calendar.MONTH), startDateCalendar.get(Calendar.DAY_OF_MONTH));
            datePickerDialog.getDatePicker().setMinDate(startDateCalendar.getTimeInMillis());
            // Create a new instance of DatePickerDialog and return itreturn datePickerDialog;
        }
        publicvoidonDateSet(DatePicker view, int year, int month, int day) {
            // Do something with the date chosen by the user
            view.setMinDate(fromDate);
            todate.setText(day + "/" + (month + 1) + "/" + year); } }

Solution 4:

you can use setMinDate and setMaxDate methods to the datepickerdialog.

eg: DatePicker toPicker = Util.getDatePicker(getActivity(), toDateSetListener, toYear, toMonth, toDay) .getDatePicker(); toPicker.setMinDate(getToMinDate()); toPicker.setMaxDate(System.currentTimeMillis());

Solution 5:

So when you close your fromDate Dialog just store the variables in class level.

fromYear fromMonth fromDay

then when you launch toDate(fromYear, fromMonth, fromDay) to the dialog then instead of calendar. get current dates, just use the from and add +1 to the day for starting the picker at the next day. Make sense?
